First, as for the differing figures on PurpleAir, it appears some indicators explicitly say they are "outdoors" and others list things like "3rd floor," which indicates they may be indoors.

Near Memorial Stadium, the purpleair sensors are showing over 300. It's the (possibly) indoor sensors that are showing around 180, but Memorial Stadium is not indoors.

My son's school (South Bay) just was sort-of cancelled for tomorrow: if a child doesn't come in, it will be an excused absence. The email from the superintendent states that this decision is "supported for all K-12 schools in Santa Clara County." The county's population is about 2 million people.

For my part, I'm packing up the family and heading to Santa Barbara for the weekend, the closest clean air I could find.
